Everyone loves a good David vs. Goliath matchup, and Russia’s M1 MMA provided an excellent one during a recent event in the Netherlands.

The fight featured ripped 271-pound French heavyweight Martin Szoltysik against the less ripped, and significantly smaller, Russian 19-year-old Kiril Sidelnikov.

The significant size discrepancy even had the announcers warning that the fight could end quickly, but the young Russian with stood several early roid rage barrages from the Mountain-like Szoltysik and eventually knocked him out cold with a perfectly placed right hand, stunning everyone.
